Abstract
Objective:
To evaluate the diagnostic value of magnetic resonant imaging (MRI) for choroidal melanoma.
Methods:
12 cases of choroidal melanoma were diagnosed by means of B-ultra-sonography, computed tomography (CT), MRI and pathology.
Results:
The MRI features of melanoma were: T(1)WI shows high signal, and T(2)WI shows low signal.
Conclusion:
Besides B-ultra-sonography and CT, MRI is also valuable in the diagnosis and differential diagnosis of choroidal melanoma.
